Recently, the coded caching (CC) technique, originally proposed by Maddah-Ali and Niesen in [1]}, has gained special attention due to an additional global caching gain compared to traditional (local) caching schemes. Encouraged by appealing CC gains, the original error-free shared medium system model of [1]} has been extended to various other scenarios such as multi-server [3]}, [4]} and wireless multi-antenna setups [5]}. Meanwhile, various practical limitations of CC are also addressed by the research community. Most notably, the large subpacketization requirement, defined as the number of smaller parts each file should be split into, is addressed in [6]}, [7]}, while the effect of the subpacketization on the low-SNR rate is investigated in [8]}.
